Having entered the open country, General Washington determined to halt a few days on the south side of this river, make some show of resistance, and endeavour to collect such a force as would keep up the semblance of an army. His letters, not having produced such exertions as the public exigencies required, he deputed General Mifflin to the government of Pennsylvania, and Colonel Reid, his Adjutant General, to the government of New Jersey, with orders to represent the real situation of the army, and the certainty that, without great reinforcements, Philadelphia must fall into the hands of the enemy, and the state of Jersey be overrun. While thus endeavouring to strengthen himself with militia, he pressed General Lee to hasten his march, and cautioned him to keep high enough up the country to avoid the enemy, who, having got possession of the mail containing one of his late letters, would certainly endeavour to prevent the junction of the two armies. This perilous state of things was rendered still more critical by indications of an insurrection in the county of Monmouth, in Jersey, where great numbers favoured the royal cause. In other places, too, a hostile temper was displayed, and an indisposition to farther resistance began to be manifested throughout that state. These appearances obliged him to make detachments from the militia of his army, to overawe the disaffected of Monmouth, who were on the point of assembling in force. [Sidenote: General Washington retreats through Jersey.] {November 23.} As the British army crossed the Passaic, General Washington abandoned his position behind that river; and the day Lord Cornwallis entered Newark, he retreated to Brunswick, a small village on the Raritan. {December 1.} At this place, the levies drawn from Maryland and Jersey to compose the flying camp, became entitled to their discharge. No remonstrances could detain them; and he sustained the mortification of seeing his feeble army still more enfeebled by being entirely abandoned by these troops, in the face of an advancing enemy. The Pennsylvania militia belonging to the flying camp were engaged to serve till the 1st of January. So many of them deserted, that it was deemed necessary to place guards on the roads, and ferries over the Delaware, to apprehend and send them back to camp. The Governor of New Jersey was again pressed for assistance, but it was not in his power to furnish the aid required. The well affected part of the lower country was overawed by the British army; and the militia of Morris and Sussex came out slowly and reluctantly.
